Issue running gulp - updated and new issues arise

Not sure what is going on here. Seems one problem after another. Running win 10 and upgraded to gulp 4 per another person recommendation as a package I wanted to use utilizes it. Anyhow, now when I run 'gulp serve', I get:

C:\Vapor\source\mission-control\dashboard (cleanup)

Not sure why this is happening now and not sure what to make of it. Any ideas please?
